Closest closed headphone to the HE400 are D2000/D5000 imo. Heard the D600 yesterday and.. no. Mad Dogs are very nice but are a bit of a mirror image of HE400 (dark and mid-centered, vs. bass and treble emphasized). Depends if you want a twin or a complement. Modding T50rps would be great fun and the best bang for your buck for a closed headphone.
